EDGAR AL AN CUSTER, or PHILADELPHIA; PENNSYLVANIA;

' MEANS: FORAUTOMAfIiCALLY CONTROLLING THE ornmi shnn oitosmo on Two-PART CASTING-MOLDS.

To all whom it may concern: Be it known that I, EDGAR A LAN CUs'rnR,

i a citizen bf the UnitedStates, residing at the 'ofPhiladelp'hi'a, in the county of Philade phia and State of Pennsylvania, have invented certain new and useful improvements in Means for Automatically Controlling the 'Opening and Closing of Two-Part Casting- I automatically controlling 'ter of Letters Patent'granted to me under (1 ate Molds, of which the following is a specificationl particularly for employment in a system of casting metal pipe orming the subject-matof November 12th, 1907, and numbered re- Q spectively,-870,817 and 870,870; and in such 'connectionjt relates to the mannerof automatical-lyclosing the respective molds mounted at suitable distances a art upon a turntable -for introducing mo ten metal 'thereinto from a cupola furnace in the formation of the pipe or other cast structures and thereafter of automatically o ening the twopart casting mold sufficient y to permitof ready withdrawal of the cast structures therefrom.

The nature and scope of my present invention will be more fully understood from the following description taken in connection with the accompanying drawings, in which Figure 1 is a to or plan view of a turntable, with one e ement of the automatic mold opening and closing means located adjacent to the table and with the other element of said means shown directly connected with .the movable cope of the mold having a long an lar arm for spanning the drag of the mo (1 and'havin a terminal rojection for engaging the inc ined groove oi said opening and closing means. Fig. 2 is a side elevational view of the automatically mold operating means, showing in this view, the mold in a closed osition, upon the turntableI Fig. 3 is a similar view, sh win the two-part mold, in an open position as well as the angular arm of, the opening and closing means in its shL'ted position; and Fig. 4 is a side elevation: l view of the inner side of one of the mold opening and closing means, showing in dotted outline'the manner in which the terminal rojection of the angular arm enters and ri es the inclined groove of said means in parting the movable cope from the sta- Specification of Letters Patent.

T tionary drag of theinold to permit of the removal then of the cast. structurefrom said mold.

containing as illustrated a series of twelve molds thereon and each composcuflf a move ablecope 6, and a stationary drag Referring to the drawings 5, is a turntable 7, hinged,

to eacl other at 8. The typemold illustrated for particularly castin metal pipe forms the, subject-matter otj'Letters Patent granted to meunderdate of May 12th,. 1908,

the tabl'e- .5, and track'9, inthe foundation, are located-stationary blocks or ,-fran1es-12 inclined groove 14, with, preferably wide flaring mouths 16 and'17, as clearl shown in Fig. 4, and which stationary bloclzs with respect to their functions as anelement of said mold .ally operating, will be hereinafter more fully descri ed. j

To each movable cope 6,'of the mold provided with a stationary drag 7, at one exan arm 18, the angular extension 19, of which is arranged to s an or embrace the drag 7, of the mold as c early shown in Fig. 3, with the movable cope 6, parted from the stationary drag 7, in which condition the cope 6, by the extension 19, of the arm 18, abutting against theunderside of the drag 7, is held in a fixed open position. -The ter-.

and No. 887,070. The turntable 5, -is arand 13, having on the inner sideof each an i opening and closing means automatictremital portion of the same is rigidlysecured minal projection 20, of the extension 19, bv

tion of travel of the terminal projection 20, Y

in such instance is indicated. by the arrows in Fig. 4, with the two part mold by such time having assumed the position shown in Fig. 3, with the cast structure in such a condition as to permit of removal of the same therefrom. v

The stationary block 12, is reveisely arranged with respect' to the block 13,-.as to the groove thereof, so that. the terminal projection 20, of an angular arm 19, of a mold by riding in a' downward direction in sume the position illustrated in Big. 2, With the inclined groove of the block 12 will close the mold "and the angular arm '19, will asthe cope 6, closed against the stationary drag 7, of the mold ready to receive molten 'metal, from the cupola furnace for the formation therein of the cast structure, as required.

:By this arrangement of the arm 18, with its angular extension 19,- connected with each movable cope of a mold it is entirely rooticable to open and to close the mold y the same movement of' the table 5, to produce in succession forward and reverse movements of thecope 6, without noise, jar or shock to the mold. ThlS is important in pipe makin %or casting operations in which an interna core is; employed to avoid cracking or breakage. thereof.

,' Having thus described the nature and -1 n combination with a-table provided with molds,' each consisting of a cope and a drag .'-and ian v lar projecting means connected with eac cope to open and close successively by the same movement of the table a co e against a drag of each of said molds, su
